5.1
Installation
Checks before installation
The structural layout must be prepared in accordance with the dimension and assembly drawings.
The concrete foundations should be of sufficient
strength (min. class X0) according to DIN 1045.
The concrete foundation must have set before the
unit is set up on it. The surface of the foundation
must be horizontal and even.
5.1.1 Ground, foundations, wall
It must be possible to set up the pump, respectively
the unit safely and stress-free on the foundations.
Distortions can cause an untimely wearing of the
pump.
Make sure that no vibrations are passed on through
the foundations.
5.1.2 Space requirements for operation and maintenance
When installing the unit, make sure that it is possible
to exchange parts of or the complete unit. Heavy
units must be equipped with appropriate facilities for
fastening and supporting lifting tools and other devices. Access routes for delivery and removal must be
provided.
5.2 Installation of the unit
During installation the unit must be leveled with the
help of the water level on the pressure connection.
Spiral casing and pressure cover will approximately assume the temperature of the pumped liquid. Pressure cover and lantern bracket must
not be insulated.
Appropriate measures have to be taken to avoid
burns.
5.3 Connecting the pipes
CAUTION
The pump must not be used as an anchor point for
pipes under any circumstances.
The pipe system must not exert any forces and momentums on the pump (e.g. by distortion or heat expansion).

When laying the suction line, make sure it ascends
towards the pump. The supply line must descend towards the pump. The pipes must be supported directly in front of the pump and have stress-free connections.
adequate distance from the drill holes for the measurement.
The set-up for the flow rate measurement must follow the regulations of the manufacturer of the measuring instrument.
The nominal diameter of short pipes must at least
equal the diameter of the pump connections. The
most economical diameter of long pipes must be determined individually.
Adaptor pieces for larger nominal diameters should
be designed with an enlargement angle of approx.
8° in order to avoid increased pressure loss.
The advisability of non-return valves and shut-off
valves depends on the type of unit and of the pump.
Suitable measures must be taken to compensate for
the thermal expansion of the pipes in order not to
strain the pump beyond the pipe forces and momentums permitted.
Exceeding the pipe forces may cause the appearance of leaky spots where the pumping
material oozes out.
Hot pumping materials may cause danger of life!
The flange covers on the suction and pressure connection must be removed before installing the piping.
Before starting the unit, the tanks, pipes and connections must be thoroughly cleaned, rinsed and air
purged. Weld beads, scaling and other impurities
often only dissolve after a long time.
5.3.1 Supplementary connections
See installation drawing or pipe layout diagram for
dimensions and position of the supplementary connection for the pump.
5.3.2 Dimensioning of the pipes
In order to avoid friction loss, the flow rate must be
max. 1.5m/s in suction or supply lines, max. 2.5 m/s
in pressure lines.
The rules of piping construction must be observed
concerning the piping layouts and the liquid quantities in order to prevent the pump from sucking air.
Dry running of the pump can cause considerable damage to pump and seals.
5.3.3 Measuring point diagram
The pressure of centrifugal pumps is measured following ISO 2548 “standardized experimental arrangements” (sketch 1, page 48).
Make sure, however, that the flow rate in the measuring pipe does not considerably exceed the values
stated in 5.3.2. If the flow rate exceeds those values,
the pressure / suction flanges must be equipped with
adaptor pieces. (sketch 2, page 48)
To ensure a reliable measurement, follow the instructions in chapter 5.3.2 and the corresponding
sketch with regard to the flow rate values when measuring pressure.
Pipe elbows, valves, adaptor pieces etc. can falsify
the measuring results and must therefore be at an

CAUTION
Fig. 5.4-3 Connection diagram for PTC thermistor
5.4.2 Timer relay setting
Make sure for three-phase AC motors with star-delta
circuit that there is a speedy switchover between star
and delta. Long intervals will cause damage to the
pump.
For star-delta circuits set the timer relay to <3 s.
5.4.3 Checking the direction of rotation
The motor’s direction of rotation must correspond to
the direction of the arrow on the spiral casing (as viewed from the motor side in clockwise direction).
Check by switching the motor on and then immediately off again.
The direction of rotation must only be checked with
the pump and the pipes primed, as important components can be destroyed if the pump runs dry.
In case of wrong direction of rotation, reverse any
two phases L1, L2 or L3 of the supply line in the terminal box of the motor.

6.1
Start-up / switching off
Initial start-up
CAUTION
Before starting the pump ensure that:
- the unit is electrically connected and all prescribed
protective measures are taken.
- the pump is filled with pumping material
After reaching operating temperature and / or in
case of leakages, tighten the hexagonal nut 920.2
or .3 or .4 after switching the unit off.
6.1.6 Switching off
Close the shutoff valve in the pressure line.
If a non-return valve is installed in the pressure line,
the shut-off valve can remain open as long as there
is back pressure.
When switching the pump off, the shutoff valve
in the supply line must not be closed.
Switch off the motor. Make sure that it coasts quietly
to a halt.
Depending on the unit the pump - after the heating
source has been switched off – should coast for long
enough to reduce the temperature of the pumped
fluid enough to prevent the heat from accumulating
inside the pump.
For a long standstill close the shutoff valve in the
supply line. Close the supplementary connections.
In order to protect the pump against frost and in case
of a long standstill, the pump should be emptied.
6.2 Operating range limits
6.2.1 Temperature of the pumped fluid
CAUTION
Do not operate the pump at temperatures higher
than those specified on the data sheet or on the rating plate.
6.2.2 Switching frequency
In order to avoid a notable increase of the temperature inside the motor and an excessive strain on the
pump, motor, seals and bearings, the following num-
7
ber of switching cycles per hour (h) must not be exceeded.
Norm block pumps 15 switching cycles per hour
6.2.3 Minimum volume
If the type of unit includes the possibility of operating
against a closed shutoff valve on the discharge side,
provide a minimum pumping volume at
t –30 bis + 70 °C ≈ 15 % von Qopt.
t >30 bis + 140 °C ≈ 25 % von Qopt.
6.2.4 Density of the pumped fluid
The power consumption of the pump changes in proportion to the density of the pumped fluid. In order to
avoid overloading of motor and pump, the density
must be consistent with the order data.
6.3 Switching off / storage / rust-proofing
Every pump is carefully assembled before it leaves
the factory. If start-up is to be delayed for any length
of time after delivery, we recommend to store the
pump as described below.
6.3.1 Storing new pumps
- New pumps are packed ready for storing in the
factory.
Protection lasts for approx. 12 months, when appropriately stored inside.
- Store the pump in a dry place.
6.3.2 Procedures for an extended non-operational
period
1. The pump remains installed and has its functions checked periodically
In order to ensure a constant operational readiness and to prevent deposits on the inside of the
pump, a test run of the pump must be carried out
(for approx. 5 min.) every 1 -3 months during a
long standstill. Only run the pump, if it is filled with
an adequate amount of water.
2. Pump is dismantled and stored
Before storing the pump it must be checked according to chapters 7.1 and 7.4. Then proceed
with rust-proofing:
- Spray the inside of the pump with preservative
agent, especially the area around the impeller
gap. Spray the preservative agent through the
pressure and suction connection. It is advisable
to close the connections (e.g. by means of plastic caps or similar).
6.4 Restart after storage
Before restarting the pump, the checks and maintenance works must be carried out according to 7.1
and 7.2.
For restarting the pump, also observe the instructions in chapter “Initial start-up” (6.1) and
“Operational range limits” (6.2).
Immediately after finishing these activities, all
safety and protection equipment must be reinstalled and reactivated.

Maintenance / Inspection
General instructions
The user has to make sure that maintenance, inspection and installation is carried out by authorized
and qualified expert staff after thoroughly studying
the operation manual.
Drawing up a maintenance schedule will help avoid
expensive repairs at minimal maintenance costs and
ensure failure-free and reliable operation of the
pump.
Principally the machine must only be worked on when disconnected from electricity.
The pump unit must be protected against accidental switch-on in order to avoid danger of life.
Pumps which convey fluids which are dangerous to health must be decontaminated.
When draining the fluid make sure to avoid any
danger for persons and the environment. Observe legal requirements to avoid danger of life!
7.2 Maintenance / Inspection
7.2.1 Monitoring
CAUTION
The pump ought to run smoothly and vibration-free
at all times.
The pump must not run dry!
Do not run the pump against a closed shut-off
valve in order to avoid heating up of the pumped fluid.
Max. permissible ambient temperature 40°C.
Storage temperature may exceed room temperature
by 50°C, but by no means rise beyond 90°C (measured on the outside of the motor casing).
For the required minimum volume see 6.2.3.
Make sure the shut-off valve in the supply line
is not closed when the pump is in operation.
A properly working mechanical seal must have no,
or only a small amount of visible leakage losses (vaporous). It is maintenance-free.
Installed reserve pumps must be operated at least
once a week by fast on and off-switching to ensure
constant operational readiness.
Watch the functioning of the supplementary connections.
7.2.2 Lubrication and lubricants
7.2.2.1 Lubrication
The roller bearings in the IEC motor are lubricated
with grease. Intervals, quality and amount are specified subsequently.
7.2.2.2 Quality of grease / grease change
The bearings are filled with high-quality, lithium-soap
grease. Under normal operating conditions the filling
will last for 15,000 operating hours or for 2 years.
Under bad operating conditions, e.g. high ambient
temperature, high humidity, dusty air, aggressive industrial atmosphere etc., the bearings should be
checked earlier and, if necessary, be cleaned.
For this purpose use grease containing lithium soap.
It should be free of resin and acid, must not become
brittle and should provide rust protection. The grease
should have a penetration value between 2 and 3,
corresponding to a walk penetration of 220 to 295
mm/10. The drop point ought not to be below 175°C.
The cavities in the bearings may only be approx. half
filled with grease.
If necessary, the bearings can be filled with greases
containing other soap bases. As greases containing
different soap bases may not be mixed, the cavities
must first be cleaned. The lubrication intervals may
have to be adjusted to the requirements of these
greases.
CAUTION
General legal requirements regarding disposal have
to be observed.
Sealed bearings with permanent lubrication (2 RSbearing or 2 Z bearing) cannot be washed out and
refilled with grease. Therefore the bearings must be
exchanged.
Motors from manufactured size 180 are equipped
with re-lubrication devices and flange lubrication
nipples in accordance with DIN 3404.
7.3 Emptying / disposal
If the pump was used for conveying fluids dangerous to health, make sure not to endanger
persons or the environment when emptying the
pump. Observe legal requirements! If necessary,
wear protective clothing and a protective mask!
7.4 Demontage
Before starting the disassembly, make sure
that the pump cannot accidentally be switched
on. The shut-off valves in the pressure / suction line
must be closed.
The pump must be at ambient temperature, depressurized and empty.
Disassembly and assembly may only be carried out
as described on the exploded drawing.
7.4.1 Basic instructions

7.4.3 Pump
Disassembly of the pump must be carried out as
described on the explosion drawing on pages 56
to 63.
7.4.4 Mechanical seal
In order to exchange the mechanical seal, it is necessary to disassemble the pump.
After removing the impeller 230 pull the mechanical
seal 433 from the shaft by hand.
Before assembly clean the shaft sleeve and remove
any scores and scratches with emery cloth, if necessary. If scoring or pitting is still visible, replace
the shaft sleeve, clean the counter-ring seat.
7.5 Reassembly
7.5.1 Pump
When assembling the pump, observe the machinebuilding regulations in force.
Before assembly brush the mating areas of the individual parts with graphite or a similar substance.
This applies equally to bolt connections.
Check O-rings for damage and replace where necessary.
As a general rule, gaskets must be replaced. Always
replace them with seals of the same thickness.
Gaskets made from asbestos-free materials or graphite must be assembled without the use of lubricants on principle.
Assembly aids should be avoided if at all possible.
However, if necessary, use a commercially available contact adhesive (e.g. Pattex) or HY-LOMAR or
Epple 33 sealant. Apply a thin film of the sealant at
selected points. Cyanoacrylate adhesive (instant
glue) must not be used.
If the sealing area between the impeller neck and
the split ring is worn, the split ring 502.1 and, if existing, 502.2 must be renewed.
Play in the gap:
new 0.3 mm in Ø
max. permissible extension to 0.9 mm in Ø

The assembly is carried out following the sequence
of disassembly in reversed order. The correct sequence of the individual parts must be maintained.
7.5.2 Mechanical seal
Installation is carried out following the sequence of
removal in reversed order. The basic rules for assembling a mechanical seal are as follows:
Maximum care, extreme cleanliness.
Only remove the contact protection from the slide
faces immediately before starting the assembly.
Avoid damaging the sealing surfaces and the
O-rings.
Clean the shaft and the counter-ring seat in the pressure cover and carefully remove deposits.
During installation of the seal, the friction forces of
the shaft sleeve 523 can be reduced by wetting its
surface with water.
CAUTION
Elastomers made of EP-rubber must never come
into contact with oil or grease.
Use water as fit-up aid.
Always press in the counter-ring into the pressurecover 163 by hand or finger. Apply pressure evenly.
